NECK-YOKE.

SPEGIFlCATIolv forming paie ofnetters Patent No. 695,075, dated April 22 1902.

Application filed September 10, 1901. Serial No. 74,975. (No model.) u V To all whom, it may concer-1e:

Be it known that I, JOHN H. SToRcH, of Wetona, in the county of Bradford, State of Pennsylvania, haveinvented certain new and useful Improvements in Neck Yokes, of which the following is a complete specification, reference being had to the accompanying drawings.

My invention belongs to that class of neckyokes in which the yoke is directly attached to a pole-tip in such manner as to afford freedom of`movement in all requisite directions to the yoke upon the pole, which permits convenient separation of the parts when required, and which prevents their accidental separation in use. 4

Theobject of my inventionv is to produce an improvementin theclass of neck-yokes referred to in which neat, economical, and effectual means are provided for limiting a yoke to a pole and in which structural provision is made for resisting such strain upon the parts which unite the two as occurs in practice. f

In the accompanying drawings, Figure I is a top plan View of my neck-yoke complete attached to a pole-tip. Fig. Il is a plan view of one of the socket members of the neckyoke, illustrating in dotted lines the pole-tip in different positions therein. Fig. III is an end View of both socket members united as in use, looking at them from the rear. Fig. IV is a section on the line IVIV of Fig. I, the parts being shown-upon an enlarged scale and the pole-tip in elevation.

Referring to the numerals on the drawings, l indicates the forward end of a pole, to which is secured in any suitable or preferredvmanner a metallic pole-tip 2. The pole-tip is provided with a bulbous or spheroidal head 3, having opposite flattened sides 4 and 5, located in practice in parallel vertical planes, as shown in dotted lines in Fig. aI, as well as in Fig. II.

6 and 7 :indicate the opposite end pieces, which united constitute my neck-yoke. They are united by a pair of metallic socket members 8 and 9 of special construction, each of the socket members being, preferably, identical in `shape and interchangeable.

The construction of each socket member is clearly shown in Fig. II and comprehends a i .hollow and substantiallyy semispherical body part 10. The lateral Vwalls of the body part 19 are respectively defined byV webs l1, which extend across the semicylindrical-end pieces'14. and 15 of the socket member. The

rear of the body part 10 is provided with an opening, which when two socket-pieces are assembled defines an aperture fitted-to receive, when properly presented, the head 3 of the pole-tip 2. Thevupper and lower sides of the opening are dened by curved iianges 16, which extend upon each socket member'from one web ll thereof to the other. These in a pair of assembled socket members, as shown in Fig. III, define a space adapted to receive the flat sides 4. and 5 of thev headB between them and to confine` the head 3 when the sides 4. and 5 thereof are disalined` with the llanges. Consequently the sides t and 5 being located in parallel vertical planes, if the, axis of the united socket members is brought into vertical alinement with them, they may f be readily applied to or withdrawn from the lpole-tip; butwhen the pole-tip is turned outl of the vertical line the head 3 ofthe pole-tip is securely confined in the `hollow or cavity or" the body part l0. 1 The iianges 16 not` only lend strength and rigidity to the socket members, but extending along a portion of the shank of the poletip 2, as shown clearly in Fig. yHLaord means for resisting twisting movements of` the yoke about its axis in any position which the yoke may assume with respect to the pole- -tip in use, as suggested, for example, in dotted lines in Fig. II of the drawings.

The end pieces 14 and l5 of the socketpieces, being semicylindrical, are adapted in an assembled pair of socket members to receive the ends of the parts 6 and 7 of the yoke,

and both they and the socket members arev united to form a complete neck-yoke, as by bolts 17. (Shown in Fig. I of the drawings.)

In manufacture the socket-pieces, respec tively comprising the body parts 10, with their webs 1l and flanges 16 and the end pieces 14 and l5, are preferably made of a single casting or forging and, being made to a standard, are universally interchangeable.

In addition to the description already given of the operation of the several parts it is necessary only to add, by way of description of- IOO the operation, that in practice a neck-yoke consisting of parts 6 and 7, duly assembled with a pair of socket members, may be applied to a pole-tip of the kind specified by bringing it into vertical position, When by tnl'ning the neck-yoke into the proper operative position the parts are united ready for use. The neck-yoke is readily removed from the pole-tip by bringing it to the position in which it was applied thereto and drawing the parts asunder.

What I claim is- 1. The combination with a pole-tip having a flattened bulbous head, of a neck-yoke provided with means for securing it to said poletp, said means comprising a hollow body part having an opening adapted to receive between its Walls the flat sides of the pole-tip, said 2. As a part of a neck-yoke, a socket mem- -ber consisting of a hollonr body part, semicylindrical end pieces, and Webs, constituting Walls of the body part and extending across the semicylindrical end pieces.

3. As a part of a neck-yoke, a socket inember consisting of a body part, semicylindrical end pieces, Webs, and a flange extending from one web to the other.

ln testimony of all which I have hereunto subscribed my name.

JOHN H. STORCH.
